Nomar Garciaparra got a jump on things today by filing for free agency as soon as humanly possible. Garciaparra joined 59 of the 200 or so players eligible for free agency that filed today.
The name that jumped out for me on the list of players which included Barry Bonds, Frank Thomas and Barry Zito was Kerry Wood. Primarily since he never showed up on the list of potential free agents that I use. While he's at the point where it's probably not worth taking a flier on him, barring any surpise moves there should be some spare room on the payroll. Maybe it could be put to use on the miniscule chance that Wood can still be a useful pitcher.
